MS-250 Mixed Signal Oscilloscope Option

The minimum high voltage level may be defined by the user (using the hysteresis controls)

up to 1.4 V above the threshold. The maximum low voltage level may be defined to 1.4 V

below the threshold. The minimum signal swing is 100 mV. The indeterminate range of 50

mV around the threshold voltage level is the level below which the MS-250 will not operate.

However, the MS-250 can support a signal as low as 100 mV only if the input signal’s

quality is adequate.

The MS-250 keeps sampling its inputs until the oscilloscope is put into STOP trigger mode.

Data is stored in a 50 Mpt internal memory that is periodically transferred to the

oscilloscope via the USB2.0 cable. If the oscilloscope is triggering in SINGLE or NORMAL

trigger mode, data is acquired and transferred only when the trigger condition is satisfied.

The captured data is then displayed on the oscilloscope grid in a time-aligned fashion.

In any trigger mode (AUTO, NORMAL, SINGLE), pressing STOP trigger cancels the

acquisition, which leaves the previously acquired data unchanged.

The MS-250 both samples incoming data and searches for trigger conditions.

The USB2.0 cable provides downloading of trigger conditions from the oscilloscope to the

MS-250 and uploading of digital data from the MS-250 to the oscilloscope.
